from scripts.regex_tester import RegexTester

# Test pattern
tester = RegexTester()
result = tester.test(r"\d{3}-\d{4}", "Call 555-1234 today")
print(result['matches'])  # ['555-1234']

# Explain pattern
explanation = tester.explain(r"\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b")
print(explanation)
